Guixu Era

Under the shadow of the vast universe lies a forgotten epic. In 2568 AD, human Federation archaeologist Lin Wan discovered a mysterious crystal on the planet γ-792c - a fragment of the "Yuanchu Star Core". This contact not only created a soul connection between her and "Watcher" Kane from a lost ancient civilization, but also revealed the truth about a cosmic war that spanned hundreds of millions of years. The "Watcher" civilization that once guarded the order of the stars has long since fallen and turned into scattered "star sand". And their mortal enemy, a cosmic plague called "Shadow" that erodes existence itself, is making a comeback under the name "Dark Devourer". Lin Wan, the scholar who accidentally became the "key", and Kane, the last watchman who awakened from a long slumber, were forced to form a strange alliance across time and space.
